Beneficiary Mining Technology-Quick-connect Spiral Drill Pipe Series
Quick-connect spiral drill pipe is developed on the basis of absorbing the advanced production technology of Germany and integrating the latest research results of our company. The drill pipe body is made of high-pressure seamless alloy steel pipe, and the spiral blade is made of high wear-resistant T-shaped steel strip, which is prestressed and wound and welded. The drill pipe joint is made of high-quality medium-carbon alloy steel, which is subjected to vacuum conditioning and high-pressure forming. This series of products adopts four-way or six-way quick connection, which is automatically locked by spring pins when used, and is equipped with U-shaped or semi-ring anti-release pins to make the torque of the drill pipe reach the best state. This series of products are mainly used with portable or hand-held drilling rigs. The drill pipe is light in weight, quickly connected, and the slag discharge speed is fast, which greatly improves the work efficiency, so it is called quick-connect spiral drill pipe. This series of products are widely used in the drilling construction of water exploration and gas exploration under the geological conditions of coal seam and near coal seam, and are divided into water type and water type. Common specifications and performance parameters are shown in the following table: quick-connect spiral drill pipe common specification model performance parameter table line number specification model mm theoretical torque N.m connection mode spiral diameter rod diameter length joint size 1 Ф 28 Ф 18500~3000F12 × 12150~200 square connection 2 Ф 30 Ф 18500~3000F12 × 12150~200 square connection 3 Ф 32 Ф 18500~3000F12 × 12150~200 square connection 4 Ф 38 Ф 21500~3000F14 × 14100~350 square connection 5 Ф 40 Ф 21~22500~3000F14 × 14100~350 square connection 6 Ф 42 Ф 22500~3000F13 × 13200~350 square connection 7 Ф 69 Ф 25~27500~3000F18 × 18250~350 square connection 8 Ф 69 Ф 25~27500~3000B20 × 20350~450 square connection 9 Ф 75 Ф 32~42500~3000F24 × 24350~450 square connection 10 Ф 89 Ф 32~50500~3000F26 × 26350~450 Quadripartite Connection 11 Ф 98 Ф 73500~3000B45 × 4510000-12000 Hexagonal Connection 12 Ф 113 Ф 63~73500~3000B45 × 458000-12000 Hexagonal Connection

Classification of Rocks-Yicang Science and Technology Drill Pipe Spiral Drill Pipe Diamond Bit Factory Outlet Rocks can be divided into three categories: 1. Magmatic rocks (spouted rocks) 2. Sedimentary rocks 3. Metamorphic rocks 1. Magmatic rocks mainly include granite, andesite, diorite, rhyolite, basalt, gabbro, etc. 2. Sedimentary rocks mainly include: quartz sandstone, lime conglomerate, mudstone, dolomite, mudstone, gypsum, etc. 3. Metamorphic rocks mainly include: gneiss, chlorite schist, phyllite, marble, mica schist, etc. Although the appearance of rocks is ever-changing, but from their formation environment, that is, from the cause of division, can be divided into rocks

The spiral drill pipe plays an important role in the drilling process. It transmits the torque of the drilling rig to the drill bit to realize drilling. In the drilling, the geological spiral drill pipe is subjected to a very complex load, almost at the same time under the tension, compression, torsion, bending and other stresses, the quality of the geological spiral drill pipe plays a vital role in the drilling work. Material and processing will cause geological spiral drill pipe to break (1) Geological spiral drill pipe material. Nowadays, the market for drilling materials is relatively chaotic, and dishonest merchants are shoddy. The vast majority of users only consider low prices, but do not have the ability to distinguish the quality of pipes and purchase them indiscriminately. Many users paid a high price and bought it.
